Exxon Elite™ 20W-50 is an oil for piston-engine aircraft. More than that, it's a premium multigrade, semi-synthetic oil. It performs the way you'd expect a premium Exxon lubricant to perform. Test after test proves it.
Exxon Elite™ 20W-50 offers advantages over other leading commercial aviation oils currently on the market. Here's what's in Elite™ for you.
Exxon Elite™ is a blend of synthetic and mineral-based oils (plus a highly effective additive package). Why a semi-synthetic? Exxon engineers determined that a fully synthetic oil may not have the solvency to handle the lead deposits that result from the use of leaded fuel. So they developed Exxon Elite™ as a semi-synthetic formulation that combines the best of both synthetics and conventional oils.
Exxon Elite™ 20W-50 is a multigrade oil with the flexibility to lubricate effectively over a wider range of temperatures than monograde oils. Compared to a monograde oil, a multigrade oil provides better cold-start protection and a stronger lubricant film at typical operating temperatures. Other benefits include lower oil consumption and better fuel economy. As a premium multigrade oil, Exxon Elite™ 20W-50 has all of these intrinsic advantages.
Exxon Elite™ has a proprietary formulation. Exxon began its development in the mid-1990s, and has refined the formulation and additive package under rigorous testing ever since.
What's in Exxon Elite™ for you? You may find that Exxon Elite™ gives you better wear and corrosion control compared to your current oil. Or better rust protection. You may even find that Exxon Elite™ is better in all of these categories.
